TMS320C6747BZKBD4

Digital Signal Processor Dsp Overview

The TMS320C6747BZKBD4 is a fixed- and floating-point digital signal processor based on the TMS320C674x DSP core, operating at clock rates up to 456 MHz. It features a two-level cache architecture comprising 32 KB L1P program cache, 32 KB L1D data cache, and 256 KB L2 unified mapped RAM/cache. The device includes 128 KB of additional shared RAM accessible by other hosts without affecting DSP performance. Key peripherals include an Ethernet MAC (EMAC), USB 2.0 OTG, three McASPs, and EDMA3 with 32 independent channels. It utilizes a 256-ball PBGA package.

Digital Signal Processor Dsp Procurement Notes

Verify silicon revision compatibility when sourcing this component, as JTAG BSDL_ID values differ between revisions 1.0, 1.1, and 2.0/3.0. Confirm that the specific ordering suffix corresponds to the required temperature range and voltage configuration, as the core voltage varies between 1.2V and 1.3V depending on the target clock frequency.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C6747 variant over the C6745 if the application requires the additional 128 KB shared RAM, Host-Port Interface (HPI), LCD controller, or USB 1.1 OHCI support. Ensure the design accommodates the 256-ball PBGA package dimensions (17 mm x 17 mm) and thermal requirements associated with the ZKB package type.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which is code-compatible with the C6000 DSP platform. It supersedes previous generations by combining C64x+ integer performance with C67x+ floating-point capabilities. The BZKBD4 suffix indicates the 456 MHz speed grade, 1.3V core voltage operation, industrial temperature range, and 256-ball PBGA packaging.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same package and pinout include other speed grades of the TMS320C6747 series, such as the 375 MHz version. Cross-family replacements require careful evaluation of peripheral availability and software compatibility due to architectural differences.
